JDM Pro data delivery process

During the data delivery process, the device communicates regularly with Jeppesen Distribution Manager Pro (JDM Pro) to determine if new content is available for download. The device downloads the content from the cloud.

The following process flow describes the major steps in the data delivery process:
  1. The device sends its real configuration to JDM Pro. The real configuration is a list of all content that is loaded on the device.
  2. JDM Pro returns the expected configuration for the device. The expected configuration is a list of all content that is assigned to and available to the device.
  3. By comparing the real configuration to the expected configuration, the device determines if new content is available to download.
  4. If content is available to download, the device gets the secure URL for each content item.
  5. The device uses the URL to retrieve the content.
  6. The device verifies the content.
  7. The device downloads the content. The content might be the full content item or a delta set. If the device downloads a delta set, the device creates the new version of the file by combining the existing version with the delta set.
